First of all, you are an amazing writer and you could definitely have a career in writing…You are being WAY hard on yourself. I tend to feel the same way, but living in fear and avoidance tends to make depression/anxiety worse. Take a chance, what’s the worst thing that could happen? Rejection? Failure? On the contrary, you may find peace and great success. I think you’re problem is overthinking, you need to get out there and take some risks. You have a talent, you are a valuable person, and you can make a difference in this world if you stop focusing on yourself.
